JOHN M. ANCK, OF PHILADELPHIA, PENNSYLVANIA.

ELECTRIC-LIGHTING GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 621,778, dated March 28, 1899.

Application filed March 24, 1 8 9 8- T0 ctZZ whom it may concern.-

Be it known that I, JOHN M. ANCK, a cilizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented anew and useful Improvement in Electric-Lighting Gas-Burners, which improvement is fully set forth in the following specification and accom panying drawlugs.

My improvement relates to that class of gas-lighting apparatus in which a spark is produced adjacent to a gas-burner by the breaking of the circuit of two electrodes connected to a source of electrical energy; and its object is to at all times keep the circuit open except only when it is desired-to light the gas, thus preventing the battery from grounding in case the movable electrode becomes caught and remains in contact with the fixed electrode, which object is accomplished by an improved mechanism, the novel details of which will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a side elevation of a gas-burner embodying my invention, showing the operative parts in normal position with the gas turned off. Fig. 2 represents a side elevation showing the lever and adjuncts in the position they assume when the gas is turned on. Fig. 3 represents a side elevation of Fig. 1. Fig. 4 represents a side elevation showing particularly the location of the spring that retains the lever on either side of its center to the burner. Fig. 5 represents a side view of the leverand its adjuncts in detached position. Fig. 6 represents a side ele-- vation showing the lever in reverse position to that shown in Fig. 1.

Similarletters of reference indicate corresponding parts in the figures.

. Referring to the drawings, A designates a gas-burner of usual construction provided with the body B and the cock 0; but while I have shown and prefer to use a valved burner my invention is also adapted to be used on a valveless burner withthe same results. Upon the valve-cock is mounted the electrode-lever D, consisting of the body portion F-and arm G, the-latter having secured thereto the laterally-extendin g member H, provided with Serial No. 674,954. (No model.)

a recess J for the reception of one end. of a spring K, the other extremity thereof being attached to any fixed point, as in the present instance to the pin L attached to the burner,

to the arm G of the lever and insulated there from by the non-conducting material N, and having its lower end M normally out of contact with the secondary or auxiliary lever P, as shown in Figs. 1, 3, and 5, which is pivoted to the extension F of the lever D by the pivot or pin Q, said lever P being adapted to be engaged by the rod X, said rod serving also in Fig. 6 by its own weight to keep the outer free end of the lever P depressed out of contact with the electrode member M, just described.

The inner end of the lever P is preferably curved, as shown at R; but it is obvious that any form which accomplishes the objects of my invention would not depart therefrom.

If desired, a spring S may be employed,having one end attached to the valve-plug or to any other suitable point and its other end adapted to operate upon the said lever P, its function being to assist in retaining said lever P out of contact with the point M of the electrode member M as well as to overpower the weights of the operating-rod X when such rod is used. This spring S'may be dispensed with without departing from the spirit of my invention, (not only when the lever P is arranged as shown in Figs. 1 and 2, but also when it is reversed, as shown in Fig. 6, in which latter the weight of the rod X will assume the function of saidspring S in retaining the lever P out of contact with the member M.)

Tdesignates the fixed electrode located in proximity to the burner or tip, said electrode having a wireU leading to any source of electrical energy.

The operation is as follows: In its normal po sition the valve-lever D appears as seen in Fig. 1 or Fig. 6, the gas being turned 01f and the lever P being out of contact with the member M, as shown in Figs. 1, 3, and 5. When it is desired to ignite the gas, the lever P is either pushed up, as in the case of the construction seen in Fig. 6, or pulled downwardly, as in the construction seen in Fig. 1, whereby said lever is caused to contact with the end M of the electrode member M, as shown at V in Fig. 2, thus making connection between said lever and member. The continued movement of said lever causes the lever D to be actuated, carrying the member M to the opposite side of the fixed electrode T, whereupon the circuit is closed and the gas ignited, said gas having been turned on simultane ously with the movement of the lever in case my invention is attached to a valved burner. Then the gas is turned on and ignited, the parts assume the position seen in Fig. 2, in which the lever P is held out of contact with the member M by the spring S, as in the other position of leverD, suchbeing the case in any position said lever D assumes and the lever P never contacting with the member H unless force is initially applied to said lever.

It is obvious that by preventing the member M from being electrically charged only when it is desired to ignite the gas, as by the insulation N and lever I, an unnecessary use of the battery is prevented, for if the movable electrode should under any condition be caught in contact with the fixed electrode, as occurs in the ordinary gas-burner, the circuit would remain closed and the battery grounded; but by my improved construction this liability and disadvantage are absolutely avoided.

I prefer under certain conditions to employ the construction seen in Fig. 6, since in said construction it is not necessary to employ the spring seen in Figs. 1 and 2 especially, al-

though in certain conditions the construction I seen in Figs. 1 and 2 might be preferable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an electric-lighting gas-burner, an electrode-lever, an insulated member secured to said lever and carrying an electrode and an auxiliary lever pivotally attached to said electrode-lever, said auxiliary lever contacting with said memberonly when it is desired to close the circuit.

2. In an electric-lighting gas-burner, an electrode-lever an insulated member supported thereby and carrying an electrode, an auxiliary lever mounted on said electrodelever and normally out of contact with said member, said auxiliary lever being adapted to contact with said member, when the cir cuit is to be closed.

3. In an electricdightin g gas-burner, a fixed electrode, an electrode-lever mounted on said burner, an insulated member secured to said lever, an electrode upon said member, and an auxiliary lever pivoted to said electrode-lever and normally out of contact with said member.

4:. An electric-lighting gas-burner consisting of a body A, a fixed electrode thereon, a valve-lever arranged to turn the gas on and off simultaneously with the movement there of, means for determining and a spring for holding said lever in either of said positions, a member secu red to said lever, insulation between said member and lever, an electrode secured to said member, a secondary lever pivotally supported and normally out of con tact with said electrode member but adapted to contact with said member when it is desired to close the circuit, and means for re taining said secondary lever out of contact with said electrode member.
